During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does.
In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one’s brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.In the last century, scientists found that a person would lose the power to do certain things _____.
| A．when he got weaker in health |
| B．if certain parts of his brain were hurt |
| C．after he did a quite different job |
| D．when he grew older |
Scientists today are still unable to show exactly ______.
| A．what each part of the brain is doing |
| B．how many chemical changes take place in the brain each second |
| C．whether each part of the brain does the same job |
| D．which part of the brain is the most important |
It has been found that one’s brain usually works ______.
| A．faster when he is old |
| B．a little now and a little then |
| C．in a very simple way |
| D．without any rest all day long |
Which of the following is NOT true according to the text?
| A．Scientists are working hard at the researches on the brain. |
| B．As many as six million chemical changes take place in the brain every minute. |
| C．A young man doing physical labor is sure to have a much slower mind. |
| D．Even an old man has a quick mind only if his brain is given much exercise. |
The more work we give our brains,___________.
| A．the less result we will gain |
| B．the more work they are able to do |
| C．the weaker their power will get |
| D．the more tired they will feel |
Muzak
The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? ____1__ It’s similar to the music you listen to, but it’s not exactly the same. That’s because this music was especially designed to relax you, or to give you extra energy. Sometimes you don’t even realize the music is playing, but you react to the music anyway.
Quiet background music used to be called “elevator (电梯) music” because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name “Muzak”. About one-third of the people in America listen to “Muzak” every day. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. ____2____.
If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don’t want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? ____3__.
Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. 4 Supermarket shoppers buy 38 percent more groceries.
___5__. They say it’s boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!
| A．Some people don’t like Muzak. |
| B．The music gives them extra energy. |
| C．Music is playing in the background. |
| D．Factory workers produce 13 percent more. |
E. Muzak tends to help people understand music better.
F. They get as much as $4 million a year if their songs are used.
G. Muzak is played in most of the big supermarkets in the world.
A new chapter in space exploration has been opened up after NASA confirmed that their mission to bomb the Moon had found “significant quantities” of frozen water.Scientists said the “exciting” findings had gone “beyond expectations” as fully formed ice was found in a crater on the planet.The water was found in one mile high dust that was kicked up by the Lunar Crater Observation and Sensing Satellite(LCOSS) last month when it crashed into the Cabeus crater near the Moon's south pole.
“Indeed，yes，we found water.And we didn't find just a little bit，we found a significant amount，”said Anthony Colaprete，project scientist and principal investigator for the ￡49 million space mission.
“This is a great day for science and exploration，” said Doug Cooke，associate administrator of NASA.“The remarkable results have gone beyond our expectations.It is incredibly exciting.”
The identification of waterice is important for purely scientific reasons，but also because a supply of water on the Moon would be a vital resource for future human exploration. The findings，which completely contradict previous beliefs that the Moon was a dry place，justify the controversial mission. Over the last decade，scientists have found some hints of underground ice on the Moon's poles，mainly in the form of compounds of hydrogen but this is the best evidence yet.
The discovery is expected to have major implications for the future of lunar exploration，and a ready supply of water could help set up lunar bases or launch missions to Mars. Mr Colaprete said that it should be possible to purify the water for drinking even though it appeared to be mixed with poisonous methanol(甲醇)． Which of the following is TRUE of the “bombing”？
| A．It damaged the Moon surface severely. |
| B．It would do harm to the space environment. |
| C．It confirmed the existence of water on the Moon. |
| D．It would help the research on Mars. |
The underlined word “NASA” in the first paragraph maybe referred to ________.
| A．a base in space |
| B．a new kind of bomb |
| C．a part of the Moon |
| D．a government department |
Which of the following is the best title of the text?
| A．Water Found on the Moon after NASA “Bombing” |
| B．Unbelievable Space Research |
| C．Possible Base on the Moon |
| D．Mysterious Water Found on the Moon |

Albert was an ordinary worker in an oil company in America. His workmates gave a nickname(绰号) “Four dollars a bucket (桶)” to him, for he was always used to leaving an advertisement of his company “Four dollars a bucket of oil” below his name whenever and wherever he wrote down his name.
As time went by, people forgot his real name. Later, when Rockefeller, the board chairman of the oil company, heard of it, he was very surprised, so he invited Albert to come to his office.
“Some people give you a nickname for ‘Four dollars a bucket’. Why aren’t you angry?” asked Rockefeller with some puzzlement in his eyes.

About a week ago, when I was playing basketball at our local park, I noticed a small group of boys picking on a smaller, skinnier boy. They were 1 him names and even 2 him to the ground and kicked dirt in his face. 3 I saw that, I walked over to the group.
I stepped 4 them and the smaller boy, and 5 them politely what this boy had done worthy of 6 they were doing to him. One of the boys replied, "He's weird (古怪的)." At that, I asked one of the boys if he thought his friend was weird, and the 7 was "No". So, I asked another boy what the word '"weird" 8 , and he said, "Different." That was my cue (暗示). I told them that everyone is 9 , and that they all looked just as different to the other boy as he did to them. They all stood 10 for a moment, and then the most 11 thing happened. One of the boys helped the small boy off the ground and then said 12 to him. What's more, he 13 to let him play with them.
I thanked the boy for being so 14 . ①As I looked around, I realized that there were dozens of other people at the park 15 no one else had stopped to help this boy. I felt 16 that the boy was strong enough to stand up against his friends to 17 someone in need. But at the same time I felt sad that 18 else had even taken a second look.
②I hope that my action helped them 19 that they could have made a difference with a little 20 , and maybe next time they will be the ones who choose to help.
